摘要： An ultrasonic element has a membrane formed as a thin walled portion of a substrate, on which a piezoelectric vibrator is formed. The piezoelectric vibrator comprises a piezoelectric thin film and metal electrode films, which are formed into a sandwiched structure. The piezoelectric vibrator resonates with the membrane at a predetermined ultrasonic wave-band frequency. A hollow-out pattern is formed in the piezoelectric thin film to divide the piezoelectric vibrator into multiple portions, wherein the hollow-out pattern is formed in such an area corresponding to stress concentrated area which appears in vibrations of the membrane in diametrical directions thereof. The membrane is made to be easily deformed in response to vibration of the piezoelectric vibrator, so that an ultrasound of a higher sound pressure can be emitted.

摘要： A receiver of an ultrasonic sensor includes reception elements, each of which has a shape of a flat rectangular plate. The reception elements are arranged one-dimensionally on a plane so that the reception surfaces face the same direction and that the reception elements are aligned with small intervals in the width direction thereof while longitudinal ends of the reception elements at a certain side are aligned in a straight line. The widths and the thicknesses of the reception elements are even, while the longitudes of the reception elements are uneven. The both longitudinal ends of the reception elements are fixed to prohibit the vibration of the ends. The longitudes are designed so that the primary resonance frequencies of the reception elements are uneven.

摘要： An ultrasonic sensor includes a transmitting device, a receiving device, and a circuit device. The circuit device determines that the receiving device receives an ultrasonic wave reflected from an object, when an output voltage of the receiving device is equal to or greater than a first threshold. The circuit device includes a humidity detection section configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment section configured to calculate, based on the detected ambient humidity, a sound pressure of the ultrasonic wave that is received by the receiving device after propagating over a round-trip distance between the ultrasonic sensor and the object. The threshold adjustment section reduces the first threshold, when the output voltage corresponding to the calculated sound pressure is less than a second threshold that is greater the first threshold.

摘要： An ultrasonic sensor includes a transmitting device, receiving devices arranged in an array, and a circuit device. One receiving device is configured as a reference receiving device. The circuit device includes a reference signal generator and first and second synchronous detectors. The reference signal generator generates a reference signal by using a received signal of the reference receiving device. The first synchronous detector performs synchronous detection of a received signal of one of the receiving devices based on the reference signal to detect a distance to an object. The second synchronous detector performs synchronous detection of received signals of the receiving devices except the reference receiving device based on the reference signal to detect a direction of the object.

摘要： In a direction detecting device, a transmitting wave generator encodes a transmitting signal with a code having a high autocorrelation so as to generate a transmitting wave. A transmitter transmits the transmitting wave and a plurality of receiver elements receives a reflected wave reflected by an object. A direction calculating unit calculates a direction of the object based on a phase difference between a correlation value calculated based on the reflected wave received by one of the receiver elements and a correlation value calculated based on the reflected wave received by another one of the receiver elements, a distance between the one of the receiver elements and the another one of the receiver elements, and a wavelength of the transmitting wave.

摘要： A detector made of lanthanum-doped lead zirconate titanate detects intensity of ultraviolet light radiated inside of a vehicle. The detector sends ultrasonic wave to an incidence direction of ultraviolet light, and detects ultrasonic wave reflected by an object. An electrical unit determines the object to be an occupant of the vehicle or not based on the reflected ultrasonic wave. The electrical unit outputs a signal representing that a predetermined or more amount of ultraviolet light is radiated to the occupant, when the detector detects the predetermined or more amount of ultraviolet light and when the electrical unit determines the object to be the occupant.
